Champion Data have crunched the numbers for every match over the next seven rounds, and have come up with the fixtures that will have the most bearing on finals positions.
According to the AFL's official statistics provider, the round 20 match between St Kilda and West Coast at Etihad Stadium is the most important match of the run home in the competition.
Should the Saints win that clash, they'll have a 71% chance to make the top eight compared to a 38% chance if they lose, while the Eagles have similar odds for a win or a loss as well.
With a 70% combined swing, that game is the most important, with St Kilda also featuring in the next three most important clashes.
Games against Richmond in round 23, Sydney in round 18 and Essendon in round 17 will see the Saints have a massive say in which teams advance to September.
Port Adelaide's trip to Melbourne looms as the most important match for a top four position with a combined swing of 62%, while Adelaide's match against Geelong next weekend having a combined swing of 70% and is the most important game in the run for the top two.
